Service in South American and Greek revolutions
In
1820, during a stay on the western coast of South America, Brommy enlisted as a midshipman in the Chilean Navy, at the time when it was led by British nobleman Lord
Thomas Cochrane, the former
Royal Navy officer who had achieved distinction in the
Napoleonic Wars. Cochrane undertook the education of young Brommy, so that the youth was soon fit to take on his first command: the 18-gun brigantine
Maypo. Brommy took part in several actions in Chile's War of Independence against the Spanish. When Brazil became an independent empire in 1822, Cochrane left Chile in order to develop a Brazilian fleet. Brommy followed him, remaining in Brazilian service until 1825.
From
1827 to
1828, Cochrane led the Greek war fleet in battle against the Turks and Egyptians. Brommy also followed him to Greece, now with the rank of Lieutenant Commander [
Korvettenkapitän]. He was initially first officer of the
Epicheiresis (the former
Enterprise), later commander of the 64-gun steam frigate
Hellas (formerly
Hope). As second in command of the corvette
Hydra, he took part on October 20, 1827 in the
Battle of Navarino, where a combined British-French-Russian-Greek fleet defeated the Turks and the Egyptians.
On June 11, 1828, Brommy was advanced to the rank of Commander [
Fregattenkapitän], and given command of a modern steam frigate. In the squadron of Greek Admiral
Andreas Vokos Miaoulis, Brommy took part in the battles in the Gulf of Arta, and participated in the recapture of Missolonghi. In 1829, during the turmoils of the third Greek civil war, Miaoulis and Brommy supported the bourgeois camp. Soon, however, Brommy left Greece and returned to Saxony. In Meissen, he published an autobiographical novel under the pseudonym R. Termo.
In 1832, the Bavarian prince Otto von Wittelsbach became
Otto, King of Greece. The King was conducted to his new realm by a Greek delegation under
Admiral Miaoulis; Brommy attached himself to this delegation, and became an officer in the Greek Navy. He was named commander of various warships, harbormaster of
Piraeus, and head of the admiralty court. Later he became first commandant of the naval school in Piraeus. In
1845 Brommy requested the Prussian King
Frederick William IV for transfer into the Prussian navy, but this request was denied.
